Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Summary
Brief summary
The AC-055-302/SERAPHIN study will be an event-driven Phase III study, comparing two different doses of macitentan (ACT-064992) (3 and 10 mg) vs placebo in patients with symptomatic PAH. The main study objective is to demonstrate that macitentan (ACT-064992) prolongs time to the first morbidity or mortality event, and to evaluate the benefit/risk profile of macitentan (ACT-064992) in the treatment of patients with symptomatic PAH.
